How to Solve PrestaShop Back Office Log Out Issue

PrestaShop had been working fine until one night when I was on the Preferences page, I got automatically logged out after saving it. I thought it was normal but the auto-logout was persistent.

Everytime I re-logged in and clicked somewhere, I got automatically logged out and redirected to the login page. Browsing through the forums didn’t help – All the solutions didn’t work. And then I remembered a similar problem I had with Joomla and that my hosting provider solved it for me.

And sure enough, I found the working solution from a hosting provider.

Edit the Cookie.php File

So here’s what you should do. Download the cookie.php file using your FTP software. The file is inside the /classes folder.

Open cookie.php and look for these codes and delete them (or preferably comment them out):

if ($this->id_employee AND Validate::isUnsignedId($this->id_employee) AND
Employee::checkPassword(intval($this->id_employee), $this->passwd) AND
(!isset($this->_content['remote_addr']) OR $this->_content['remote_addr'] ==
ip2long(Tools::getRemoteAddr())))

Replace the codes above with this:

if ($this->id_employee AND Validate::isUnsignedId($this->id_employee) AND
Employee::checkPassword(intval($this->id_employee), $this->passwd))

For version 1.4, look for the codes below and comment the first line out.

AND (!isset($this->_content['remote_addr']) OR
$this->_content['remote_addr'] == ip2long(Tools::getRemoteAddr()))

It should look like this:

//AND (!isset($this->_content['remote_addr']) OR
$this->_content['remote_addr'] == ip2long(Tools::getRemoteAddr()))

Now clear your browser cache and restart your browser. The auto-logout issues should be resolved now.
It worked for me; I hope it does for you. Good luck!
